Arandaspida is a taxon of very early, jawless prehistoric fish which lived during the Ordovician period.
The eyes, surrounded by a sclerotic ring, are housed in a notch at the anterior end of the dorsal shield.
The body is covered with rod-shaped scales arranged in chevrons, and the tail is probably pad-shaped and diphycercal.
Taxonomy based on the work of Mikko's Phylogeny Archive,[2] Nelson, Grande and Wilson 2016[3] and van der Laan 2018.
